1 Claim.

This invention relates to a reservoir tooth brush and it consists in the constructions, arrangements and combinations herein described and claimed.

It is the cardinal object of the invention to provide a tooth brush wherein a brush head is operatively connected with a hollow handle therefor, for storage of a powder dentifrice, the head and handle providing a controlled discharg outlet for the dentifrice.

More specifically, it is an object of the invention to provide a brush head having a threaded shank, the outer end of which is formed with a pocket, a hollow handle interiorly threaded is provided for engagement with the threaded shank, the handle having a discharge opening adapted to register at times with the pocket of the shank, for discharge of powdered dentifrice contained within the handle.

It is also an object of the invention to provide a tooth-brush of the character described, in which a cover member is employed for housing the brush head when not in use, the cover including a clip device for detachably securing the brush within a pocket of a garment or the like.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a side elevation of the brush with the cover attached.

Figure 2 is a similar view with the cover re moved, the dentifrice discharge opening being in closed position.

Figure 3 is a view at right angles to Figure 2, the handle of the brush having been rotated to bring the discharge opening into operative position with a pocket formed in the shank of the brush head.

Figure 4 is a longitudinal section on the line 4--4 of Figure 3.

Figure 5 is a cross section on the line 55 of Figure l.

Attention is first invited to Figure 1 of the drawing, wherein there is shown a tooth brush generally indicated by the reference character H1, consisting of a brush head II and a hollow handle l2 threadedly connected together, as will now be explained.

of the shank tapers eccentrically toward and merges into the front face [4 of the brush head, as well as into the portion I! of the shank. By thus forming the head and shank, the bristles may be readily and efficientl presented to th teeth of a user.

The shank l6 terminates in a cylindrical threaded ferrule l9 and has threadedly engaged therewith the hollow handle l2.

As shown in Figures 4 and 5, the end of the ferrule I9 is formed with a pocket 2!! extending from the end 2| of the ferrule inwardly toward the shank 16 a distance and terminating at the periphery of the portion l1 thereof, where said portion is formed with an indicator mark 22 establishing the position of the pocket when enclosed within the handle.

The handle I2 is of cylindrical tapering form, the open end being slightly bevelled as at 23, so as to merge into continuity with the shank of the head. A dentifrice discharge opening 24 is formed in the handle l2 located at a point so as to register with the pocket 20 when the handle is partially rotated to bring the indicator mark 25 in alignment with the mark 22 of the brush head, and preferably the handle will have an arrow 26 adjacent the discharge 24 to indicate the direction of rotation to align the opening with the pocket. The pocket 20 is here shown as bein of segmental shape, forming a pocket of substantial area, thus feeding the dentifrice to the discharge opening of the handle. It will be understood that the brush head may be completely removed from the handle for filling purposes.

In use, with the brush head and handle in the closed position as shown in Figure 2, and it is desired to dispense the dentifrice from the handle, the head H is held stationary in one hand while the handle I2 is rotated in th direction of the arrow 26 until the mark 25 of the handle registers with the mark 22 of the brush head. The discharge opening and the pocket are thus in registry and the dentifrice is free to flow into the palm of a hand of the user and when the desired amount has been deposited, the handle is rotated in a direction opposite to that indicated by the arrow, thereby closing the dischargeopening by reason of non-registry of the opening and pocket. The brush may be then used as is ens- 3 of apertures 28 permitting a circulation of air to permit proper drying of the brush bristles. In order that the brush may be carried in the pocket of a garment or otherwise, the cap includes a conventional clip device 29.

While I have shown and described a preferred form of the device, this is by way of illustration only, and I consider as my own all such modifications in construction as fairly fall within the scope of the-appended claim.

I claim:

In a reservoir tooth brush, a brush head having a shank and an integral threaded ferrule, a hollow handle threadedly engaged upon the fer rule, the inner end of the ferrule having a forwardly inclined segmental shaped pocket opening upon the periphery of the :ferrule for trecep tion of powdered dentifrice contained within the handle and said handle having an exteriorly opening discharge located so as to register with said pocket upon a partial rotation of said handle.
